How many sections does the Excelle exhaust pipe have?
1 Answers
The Excelle exhaust pipe consists of four sections, including the exhaust pipe, catalytic converter, muffler, and tailpipe. Below is more information about automotive exhaust pipes: 1. Exhaust pipe composition: The exhaust pipe is part of the engine's exhaust system, which mainly includes the exhaust manifold, exhaust pipe, and muffler. Typically, the three-way catalytic converter for controlling engine pollutant emissions is also installed in the exhaust system. The exhaust pipe generally includes the front exhaust pipe and rear exhaust pipe. 2. Types of automotive exhaust pipes: (1) S-type: Enhances torque at low to medium RPMs, providing quick acceleration and strong climbing power. It produces a deep sound and does not sacrifice high-RPM horsepower when the noise level is around 90 decibels. It mainly extends the formation of exhaust gases to achieve power enhancement. (2) Internal backpressure: Specifically designed according to the vehicle's characteristics. It improves low to medium RPM torque without being noisy. (3) G-type: Used for large-displacement engines above 2.0 liters. It reduces noise through three-stage backpressure and extends the form of airflow. (4) Straight pipe: Enhances high-RPM horsepower but offers little improvement in low to medium RPM torque. It is more suitable for long-distance high-speed driving and racetracks. The noise level is around 100 decibels, which is relatively loud.
